At the interface level of the system, the CPU of the storage server processes the service data, converts the PCIe bus led out by the CPU into an SAS bus protocol through an SAS (Serial Attached SCSI, serial attached SCSI protocol) controller, and then is connected to the hard disk through the SAS bus.

Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 2, a flowchart of a method for checking hard disk failures provided in an embodiment of the present invention may include:
s11: and monitoring an in-place signal of each hard disk slot on the storage server, and determining any hard disk as a target hard disk when determining that any hard disk currently exists and is inserted into the corresponding hard disk slot based on the in-place signal.
The execution body of the method for checking the hard disk failure provided by the embodiment of the invention can be a corresponding device, and the device can be arranged on an SAS bus controller, so that the execution body of the method can also be the SAS bus controller, and the execution body of the method is specifically described below as the SAS bus controller. The hard disk insertion system is that a hard disk is inserted into a hard disk slot connected with the SAS bus controller; in addition, the CPLD (Complex Programmable Logic Device ) is a module for monitoring hardware signals on the storage server, after the hard disk is inserted into the system, the hard disk (because the hard disk is inserted into the hard disk slot, the hard disk corresponds to the inserted hard disk slot, and the in-place signal of the hard disk is the in-place signal corresponding to the hard disk slot) is pulled down, so that the CPLD judges whether the hard disk in the hard disk slot is in place, the judged in-place state (the value of the in-place signal) is written into the CPLD register, the SAS bus expander queries the in-place states of the hard disks in all the hard disk slots from the CPLD register, if the state that the hard disk is not in place is found for one second, the state that the hard disk is in place is just inserted is described, and the SAS bus expander can record the time at this moment as the reference time for judging whether the hard disk is in fault.
The SAS bus expander can query the in-place state of all hard disks in real time or at fixed time, such as once every second or once every ten seconds, and the like, and can be specifically set according to actual needs; of course, it is also possible that the CPLD register reports the in-place status of all hard disks to the SAS bus expander in real time or at a fixed time for the SAS bus expander to determine the in-place status of each hard disk based on the information reported by the CPLD register.
S12: starting timing from the moment that the target hard disk is inserted into the corresponding hard disk slot, and determining that the target hard disk is a fault disk if the time length obtained by timing reaches a time length threshold and the target hard disk cannot realize normal connection with the corresponding expander.
It should be noted that, when determining that any hard disk is currently inserted into the corresponding hard disk slot based on the in-place signal, the time of the hard disk inserted into the corresponding hard disk slot can be recorded, so as to facilitate corresponding timing. The expander is an SAS bus expander, and the purpose of inserting the hard disk slot is to insert the corresponding SAS bus expander, so that the connection with the system is realized through the SAS bus expander; after the hard disk is inserted into the system, normal connection with the corresponding expander can be realized in tens of seconds, so that normal work can be realized, the normal response to an upper instruction and the like is included, and the state can be called hard disk connection; the process of inserting the hard disk into the system until normal connection with the corresponding expander can be realized comprises the steps of starting the hard disk, realizing signal connection between the hard disk and the SAS bus expander, and the like, and further realizing the receiving of upper-layer instructions, corresponding feedback and the like through the SAS bus expander. After determining the destination hard disk, the connection state of the hard disk can be queried in real time or at fixed time, namely, whether the hard disk is connected or not is determined, whether the time length obtained by starting timing at the moment of inserting the destination hard disk into the system reaches a time length threshold value is determined, if the time length threshold value is reached but the connection of the hard disk is not realized (normal connection with a corresponding SAS bus expander cannot be realized), the connection of the destination hard disk is considered to be overtime, and the connection cannot be realized normally, so that the destination hard disk is determined to be a fault disk at the moment, and if the time length obtained by starting timing at the moment of inserting the destination hard disk into the system does not reach the time length threshold value and the connection of the hard disk can be realized, the destination hard disk is indicated to be normal. In addition, the duration threshold may be set according to the time required for the hard disk connection under normal conditions, specifically, the duration threshold may be set to a value greater than the number of seconds within ten seconds of the time required for the hard disk connection, and if fifteen seconds are required for the hard disk connection under normal conditions, the duration threshold may be set to twenty seconds, so that it can be ensured that the duration threshold can fully satisfy the time required for the hard disk connection.
S13: and sending the information of the target hard disk as the fault disk to a corresponding operating system, and simultaneously, lighting a fault lamp corresponding to the slot position of the hard disk inserted by the target hard disk.
When the hard disk is not successfully connected, the operating system cannot identify the hard disk which is not connected, and therefore a fault alarm of unsuccessful connection of the hard disk cannot be generated. Therefore, in this embodiment, after determining that the connection of the hard disk is overtime and the hard disk is a failed disk, the information of the hard disk that the hard disk is not failed can be sent to the operating system, so that the user can obtain the information from the operating system and instruct the hard disk that the connection cannot be successfully realized, thereby reminding the user of replacing the failed disk in this way. Meanwhile, the SAS bus expander can also light a fault lamp corresponding to the slot position of the hard disk through the CPLD so as to prompt a user to determine the position of the fault disk in the machine room, and the user can conveniently replace the corresponding fault disk.
In addition, after the destination hard disk is determined to be the fault disk, the hard disk can be marked as the fault hard disk, specifically, the hard disk can be marked at the corresponding position in the SAS bus expander, or the hard disk slot into which the hard disk is inserted can be marked, so that the state of the hard disk can be conveniently known.
According to the technical scheme, through monitoring the in-place signals of all hard disk slots on the storage server, when any hard disk is inserted into the corresponding hard disk slot, timing is started at the moment of hard disk insertion, if the time length obtained by timing is longer than a time length threshold value and normal connection of the hard disk with the corresponding expander cannot be achieved, connection timeout of the hard disk is indicated, a corresponding user is reminded of replacing the hard disk in a mode of sending the information to an operating system, meanwhile, the position of the hard disk in a machine room is prompted by a mode of lighting a fault lamp corresponding to the hard disk slot, so that the state of hard disk faults can be identified when the hard disk fails and cannot be connected to a system, corresponding warning occurs, and a user is prompted to replace the hard disk in time.
The method for checking the hard disk faults provided by the embodiment of the invention can further comprise the following steps:
if the time length obtained by timing does not reach the preset time length and the target hard disk can realize normal connection with the corresponding expander, self-checking information obtained by detecting the target hard disk by the target hard disk is obtained at regular time;
extracting bad block proportion contained in the self-checking information, if the bad block proportion reaches a proportion threshold value, executing the step of determining that the target hard disk is a fault disk, otherwise, determining that the target hard disk can be continuously used; bad block proportion is the proportion of bad blocks contained in the target hard disk to all data blocks contained in the target hard disk.
It should be noted that, the hard disk may detect itself at regular time, and the detected result includes whether there is a bad block in the hard disk, the proportion of the bad block in the hard disk to all the data blocks in the hard disk (bad block proportion), and then store the detected result as self-checking information. If the hard disk is successfully connected in a reasonable time (the time obtained by timing does not reach the preset time), self-checking information in each connected hard disk can be obtained at fixed time or in real time, if the proportion of bad blocks contained in the self-checking information reaches a proportion threshold value, the hard disk is seriously damaged, so that the step of determining that the hard disk is a fault disk can be executed, otherwise, the hard disk is considered to be continuously used, and therefore, the effective monitoring on whether the hard disk can work normally is further realized in the mode. In addition, the ratio threshold may be set according to actual needs, such as fifty percent.
In addition, if the time length obtained by timing does not reach the preset time length and the target hard disk can realize normal connection with the corresponding expander, the SAS bus expander scans all the hard disks which are normally connected with the SAS bus expander and comprise the target hard disk, broadcast is sent to the SAS controller, an operating system on the CPU confirms how many hard disks are in the equipment through the SAS controller, the allocation of the drive letter to each hard disk is uniformly managed, and if the hard disk cannot respond to the instruction of the operating system within a certain time, the operating system judges that the hard disk has faults and generates an alarm.
The method for checking the hard disk faults, provided by the embodiment of the invention, further comprises the following steps after the bad block proportion contained in the self-checking information is extracted:
if the bad block proportion is not zero, the priority of the destination hard disk is obtained, if the priority of the destination hard disk reaches the priority threshold, the step of determining that the destination hard disk is a fault disk is executed, if the priority of the destination hard disk does not reach the priority threshold, the step of determining whether the bad block proportion reaches the proportion threshold is executed, and if the bad block proportion is zero, the destination hard disk can work normally.
The priority threshold may be set according to actual needs, for example, a priority of 1 to 10 may be set for each hard disk, and the priority threshold may be set to 7, 8, or the like. When the proportion of the bad blocks is not zero, the existence of the bad blocks in the hard disk is indicated, at the moment, the priority of the hard disk can be checked, if the priority of the hard disk reaches a priority threshold, the priority of the hard disk is indicated to be high enough, and the requirements on the safety and the reliability of the data stored in the hard disk are high enough, so that the step of determining the hard disk as a fault disk can be directly executed as long as the existence of the bad blocks in the hard disk is indicated to ensure the safety and the reliability, and adverse effects caused by the bad blocks are avoided; if the priority of the hard disk does not reach the priority threshold, it indicates that a small amount of damage to the hard disk can be allowed, so that the step of determining whether the bad block proportion reaches the proportion threshold can be performed. In this way it is further ensured that the hard disk conditions meet the current demands for it.
The method for checking the hard disk fault provided by the embodiment of the invention can further comprise the following steps after determining that the time length obtained by timing reaches the time length threshold and the target hard disk cannot realize normal connection with the corresponding expander:
and attempting to control the destination hard disk to realize normal connection with the corresponding expander, if the attempt is successful, determining that the destination hard disk can realize normal connection with the corresponding expander, and if the attempt is failed, executing the step of determining that the destination hard disk is a fault disk.
After the hard disk connection is overtime, the SAS bus controller may try to connect with the hard disk again, for example, send a signal to the hard disk to determine whether the hard disk can connect based on whether the hard disk is fed back, so that the accuracy of the determination of whether the disk is a failed disk is further ensured through the attempt.
The method for checking the hard disk faults provided by the embodiment of the invention, based on the in-place signal, determines that any hard disk is inserted into the corresponding hard disk slot, and can comprise the following steps:
if the bit signal of any hard disk slot is changed from high level to low level, it is determined that any hard disk slot is inserted into the hard disk.
The SAS bus expander checks the on-site state of the hard disk in time or in real time, and when the on-site signal of the on-site state of the hard disk is changed from non-on-site to on-site, the hard disk insertion system can be determined; in order to facilitate the information to be obtained, in this embodiment, the corresponding in-place signal may be made to be high level when the hard disk is inserted into the corresponding hard disk slot, and the in-place signal may be pulled down after the hard disk is inserted, so that the hard disk insertion is determined after the in-place signal is changed from high level to low level, and this information obtaining manner is fast and effective.
The method for checking the hard disk fault provided by the embodiment of the invention can further comprise the following steps after determining that the target hard disk is the fault disk:
and sending the information of the target hard disk as the fault disk to a preset management terminal.
In addition, in order to facilitate the user to remotely acquire the information of the hard disk as the fault disk, the information of the hard disk as the fault disk can be sent to the operating system and the fault lamp is indicated to be lightened, and meanwhile, the information of the hard disk as the fault disk can be sent to the terminal of the user, namely the preset management terminal, so that the user is further ensured to replace the hard disk in time.
The SAS bus expander regularly inquires the in-place state and the connection state of the hard disk, so that the hard disk which cannot be normally connected to the system is arranged, a user is prompted to replace the hard disk through corresponding alarm, and the problem that an operating system cannot arrange a fault hard disk in a scene that the hard disk is not connected is solved.
